RabbitMQJava系列1-简单队列

P：生产者

C：消费者

红色的图标为队列，代码实现：

一、工厂工具类

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class ConnectionUtil {

public static Connection getConnection() throws IOException, TimeoutException{
//连接工厂
ConnectionFactory connectionFactory = new ConnectionFactory();
//设置服务地址
connectionFactory.setHost("127.0.0.1");
//设置端口 AMQP协议
connectionFactory.setPort(5672);
//设置虚拟主机vhost
connectionFactory.setVirtualHost("/vhost_mmr");
//设置用户名，密码
connectionFactory.setUsername("user_mmr");
connectionFactory.setPassword("123");

return connectionFactory.newConnection();
}
}

二、 消息生产者

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.zy.rabbitmq.util.ConnectionUtil;

/**
* 消息生产者
*
* @author zy
*
*/
public class Send {
private static final String QUEUE_NAME = "test_simple_queue";

public static void main(String[] args) throws IOException, TimeoutException {
// 获取连接
Connection connection = ConnectionUtil.getConnection();

// 从连接中获取一个通道
Channel channel = connection.createChannel();
// 创建队列声明
// String queue, boolean durable, boolean exclusive, boolean
// autoDelete,Map<String, Object> arguments
channel.queueDeclare(QUEUE_NAME, false, false, false, null);

String msg = "hello simple !";

// 发送
channel.basicPublish("", QUEUE_NAME, null, msg.getBytes());

System.out.println("--send msg:" + msg);

channel.close();
connection.close();
}
}

三、消息消费者

/**
* 消费者消费消息
*
* @author zy
*
*/
public class Receive {

private static final String QUEUE_NAME = "test_simple_queue";

public static void main(String[] args) throws IOException, TimeoutException {
// 获取连接
Connection connection = ConnectionUtil.getConnection();
// 从连接中获取一个通道
Channel channel = connection.createChannel();
// 队列声明
channel.queueDeclare(QUEUE_NAME, false, false, false, null);

//基于事件
Consumer consumer = new DefaultConsumer(channel) {
@Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties,
byte[] body) throws IOException {
String message = new String(body, "UTF-8");
System.out.println(" receive msg:" + message);
}
};

// 监听队列
channel.basicConsume(QUEUE_NAME, true, consumer);
}

}

生产者将消息放入名为test_simple_queue的队列中，消费者从该队列中消费消息
